Abstract
In this paper we study residual spatial error indicators for a parabolic equation already discretized with respect to the time variable and approximated with the mortar finite element method. A posteriori error estimates are given at each step of time and are based on a local residual, the jumps of the normal derivative through the interfaces between elements and the jumps of the discrete solution through the mortars.
